#### Partially hyperbolic diffeomorphism by surgery

In this posting I will explain a surgery construction of a weakly partially hyperbolic diffeomorphisms on a closed 3-dimensional manifold. A diffeomorphism is weakly partially hyperbolic if it admits an invariant dominated splitting , where is uniformly contracting. 929 more words

#### Bing's wild involution

An embedded circle separates the sphere into two connected components; this is the Jordan curve theorem. A strengthening of this fact, called the Jordan-Schoenflies theorem, says that the two components are disks; i.e. 2,426 more words
